Comment 1 Daniel Walsh 2014-05-21 17:50:17 UTC 
This very well could be an issue with docker.  It is being discussed here.

https://github.com/dotcloud/docker/issues/4846


When you try to login, we see an error.



"PTY allocation request failed on channel 0"
Comment 2 Petr Lautrbach 2014-05-22 08:09:19 UTC 
I've built an sshd docker container using fedora-dockerfiles on rawhide, changed ENTRYPOINT [1] and I'm not able to log in indeed, but I don't see "PTY allocation request failed on channel 0" message. However there's a PAM issue [2]. 

So it'd be nice to have a reproducer that we can be sure that we are trying to solve the same problem.


[1] ENTRYPOINT ["/usr/sbin/sshd", "-D", "-ddd"]

[2] 
debug1: PAM: establishing credentials
debug3: PAM: opening session
PAM: pam_open_session(): Cannot make/remove an entry for the specified session
Comment 3 Tomas Mraz 2014-05-22 09:15:53 UTC 
From the github discussion it seems that it is regression in docker.
Comment 4 Tomas Mraz 2014-05-22 10:42:39 UTC 
Please try pam-1.1.8-11.fc21 in Rawhide.

Jeremy, have you tried the new pam package?
